Definiert in:

Returns whether the author of the supplied post has the specified capability.

This function also accepts an ID of an object to check against if the capability is a meta capability. Meta capabilities such as edit_post and edit_user are capabilities used by the map_meta_cap() function to map to primitive capabilities that a user or role has, such as edit_posts and edit_others_posts.

Example usage:

author_can( $post, 'edit_posts' );
author_can( $post, 'edit_post', $post->ID );
author_can( $post, 'edit_post_meta', $post->ID, $meta_key );


function author_can( $post, $capability ) {
	if ( ! $post = get_post( $post ) ) {
		return false;

	$author = get_userdata( $post->post_author );

	if ( ! $author ) {
		return false;

	$args = array_slice( func_get_args(), 2 );
	$args = array_merge( array( $capability ), $args );

	return call_user_func_array( array( $author, 'has_cap' ), $args );
